With Your Own Two Hands by Seymour Bernstein

Excerpts from "With Your Own Two Hands" by Seymour Bernstein
===============================================

GROUNDED
=========
Like how you pivot when you play basketball. If you pivot to the right, you anchor weight of body on right foot, freeing your left foot so that you can pivot right.
When playing piano, the weight of your arm is anchored by means of one finger which instantaneously frees the other fingers.
->Grounded within one hand; eg. hold down thumb and other fingers play
->Grounded between hands; eg LH hold down bass octave while RH running passage.

MEMORY
========
"The study of music contributes to the exercise and acumen of the mind"
-Athenaeus
(referring to memorization as one of the many educative features assoc. with the disciplines of music)

Leaps- try practising with eyes closed

If you play too carried away with emotion, feelings were not sufficiently supported by reasoned analysis and playing lacked security. (if suddenly you look at your hands and ask yourself what's next, that will induce a memory lapse) On the other hand, if rely heavily on analysis, lose contact with sublimity of the passage and end up tedious and boring.
Therefore, confront the keyboard in all its shiftings of pattern without ever losing touch with emotional involvement in the music. Only then would you have earned the right and the confidence to look up or away from the piano if you wished. Musical spontaineity can be sustained only by that synthesis of thought and feeling that makes eye contact with the keyboard or even lack of it, immaterial.
